COIN-CONTROLLED MEASURlNG-FAUCET.

SPECIFIGATION'forming part of Letters Patent No. 410,948, dated September 10, 1889.

Application filed May 6, 1889. Serial No. 809,681. (No model.)

To aZZ whom it may concern:

Be it known that I, CLARENCE 0. WHITE,

a citizen of the United States, and a resident of the city of Minneapolis, county of Helmepin, State of Minnesota, have invented a certain new and useful Coin-Controlled Measurin g-Faucet, of which the following is a specification, reference being had to the accompanying drawings.

My invention has for its object to provid a measuring-faucet of simple construction capable of use with or without a coin-controlling device. To this end 1' preferably construct the head of the faucet of two communicating sections formed integral with each other, one of which is continuous with the discharge-spout and the other of which serves as a seat for valves adapted to cut off or put the faucet into communication with the liquid contained in the reservoir. The valves are so constructed that they may be operated to open the faucet from the exterior of the tank and that they will automatically close the faucet after the channel has been held open for a certain interval of time. I preferably combine with the valves a coin-controlling device for opening the same. The coin-controlling device may be of any suitable construction adapted for the purpose.

In the drawings, like letters referring to like parts throughout, Figure 1 is a vertical longitudinal section through a tank and faucet constructed in accordance with my invention. Fig. 2 is a plan view of the faucet and the 3 5 coin-controlling device detached, some of the parts being broken away. Fig. 3 is a section on the line X X of Fig. 1; and Fig. 4 is a sectional view of a modification, some of the parts being broken away.

A is the tank for containing the water or other liquid.

B B is the faucet, of which 13 is the valveseat section, and B the discharge-spout. The valve-section is provided with openings 1) and 5 b, and the two sections are in communication with each other through an opening I) in their adjacent wall in line with the opening I). The section B is provided with a vertical lug l3 having a hole in line with the axis of the valve-section B.

C and D are a pair of valves closely fitting the interior of the valve-section B. As these valves differ in their times of movement, they are hereinafter referred to as differentiallytimed valves. Ofthese the valve D is provided with a hollow stem cl, extending outward through the hole in the lug B, and having on its extremity a transverse slotted arm d. The body of the valve D has a longitudinal perforation in line with its axis. The valve C is provided with a solid stem 0, passing through the longitudinal perforation in the valve D and extending to near the end of the hollow stem d. The stem 0 is screwthreaded at its outer end, and is provided with a screw-threaded collar 0, working thereon.

Encircling the stem 0 between its collar 0 and the end of the valve D is a coiled spring E of low tension.

Encircling the hollow stem d of the valve D between the lug B" and the end of the valve D is a coiled spring F of comparatively high tension.

Pivoted to the discharge-spout of the faucet or other support, at some convenient point, is a bell-crank lever G, one arm of which 9 is extended upward, and is adapted to pass freely through the vertical slot in the arm d on the stem cl, and the other arm of which is provided with a push-head g. I

H is a coin seat or rest, which, as shown, is an outwardlyprojecting lug on the faucet directly below the arm (1'.

K is a coin-conduit adapted to conduct the coin to the seat H between the inner end of the lever G and the inside of the arm (1, across the vertical slot therein.

L is a receptacle of any kind for catching the coin, said receptacle being attached in any suitable way to the discharge-spout of the faucet.

M represents a coin in position between the inner end of the lever G and the arm d.

The outer end of the hollow stem cl of the valve D is left open for the admission of air and the adjustment of the collar 0 on the stem 0.

The operation is as follows: The head of the faucet is inserted within the tank in the customary way, the relative positions of the two sections of the faucet being such as to bring the valve-section B on the inside of the tank. The opening 1; in the end of the valvesection B is relatively small as compared to the openings 1) and b, which are of the same size. In the absence of a coin on the seat H between the inner end of the lever Gand the arm (1 if the push-button g be depressed, the arm g will pass freely through the slot in the arm (1', and no effect will be produced on the valves. If, however, a coin be in position on the seat H, depression of the lever G will pull outward the stem (1 and the valve D, throwing the faucet in communication with the tank through the openings 1) and b. In the outward movement of the valve D it passes freely over the stem of the valve 0, compressing the coiled springs E an d F. The valve C remains for an instant in its normal position, and is drawn forward toward the valve D by the latters pressure on spring E with a slow movement, as the water is gradually admitted behind the same through the small opening 1) until it is flush against the end of the valve D, when it will close the openings 1) and b". Theinterval in time between the outward movement of the valve D and the following movement of the valve C may be made as short or as long as desired by properly graduating the spring E and the opening 1). During this interval, whatever it may be, water will fall freely through the openings 1) and l)" and out through the discharge-pipe of the faucet. On releasing the lever G the spring F will force the valves back to their normal position, removing the coin from the seat- II, whence it falls into the receptacle L. In other words, the principle of the faucet is difference in time between the movement of its valves. The valve D, fitting loosely on the stem 0, permits atmospheric pressure to take effect on the outer face of the valve C, tending to hold the same in its innermost position against the spring E when the valve D is moved outward. The spring E must, therefore, be of less tension than the atmospheric pressure on the outer face of the valve 0, but so graduated with reference thereto that when the water or air flows in through the opening I) the spring will draw the valve (J outward against the inner face of the valve D.

It is evident that instead of using the water in the tank to fill the temporary vacuum behind the valve an air-tube N might be attached to the opening I) of the valve section 13, extended outward through a tight joint to the exterior of the tank A, as is illustrated in Fig. at.

It is equally evidentthat in case it is not desired to use the coin-controllin g device with the valve D it might be operated by .hand through its stem (Z. \Vhen used as a coin-controlled device, the coin-receptacle is so constructed as to incase and inclose all parts of the stem (Z.
